I have never bet up to 1200+ spins but I only use a small part of my money to gamble. I never imagined how much money will be used to do 1200+ spins but I guess it will depend on how much money we use for one spin.
To get the jackpot is very difficult because it depends on how lucky we are in gambling games. The more people try their luck, the more money they will spend. And it can lead them to get more losses.
It is just a method to use if you really want to handle that. Nobody says that you should be doing 1200+ version of it because that is too much and I am sure that you are not going to be wanting something like that if you do not have too much money or time. However, if you really want to aim at that and you do not have that much money then I would totally understand someone who would be fighting for something like that. It doesn't take too much money but it does take a lot of time.
There are just some people in the world who are not in financially straining situation and they have a lot of time and money to test these things so it is totally understandable for those people to test it out. You and me or people like us may not have the money or more realistically we may not have the money to test something like that, this is why we do not even try for it.
